Abstract
When the velocity of gases and liquids is measured using the Doppler e ffect, burst frequencies of up to 100 MHz can arise. This paper shows how the signals can be sampled and processed with sampling frequencies of 300 MHz. A new method of sampling frequency adaption is presented to give a very large range of burst frequencies. A special ASIC has be en developed.
